I'm running a FML 6.3 server, but when I use command blocks to set my spawnpoint and then get killed or use /kill, it gives me an internal server error as soon as I hit the respawn button then disconnects me from the server. If I relog and click respawn, same thing happens. The only fix I found was to create a new world, but that's not really a fix. Any help?

Logs?

This is what the server says: [WARNING] Failed to handle packet for "player"/109.72.33.186: java.lang.NullPointerException

Where "player" is my username or anyone elses username

It looks like your command block is setting null to your spawn point, let's see your code.

What code do you need?

Whatever is in the command block.

Here you go: spawnpoint @p 30 21 140
